STEAM- SPECIFICATION forming part of Letters Patent No. 363,300, dated May 17,1887. Application filed December 14, 1 886. Serial No. 221,531. (No model.)

To all whom it may concern:

Be it known that we, FINLAY W. Ross and CARL I. HENRIKSON, both of Prentis Bay,in the countyof Mackinac and State of Michigan, have invented a new and Improved Steam- Engine, of which the following is a full, clear, and exact description.

The object of our invention is to provide a new and improved steam-engine, which is simple and durable in construction and very effective in operation.

The invention consists in the construction and arrangement of parts and details and comblnations of the same, as will be fully described heremafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawlngs, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan View of our improvement. Fig. 2 is a side elevation of the same with the fly-wheel removed. Fig. 8 is a longitudinal sectional elevation of the same on the linear a." of Fig. 1, and Fig. 4 is a rear elevation of the same.

In the middle of a suitable frame, A, is mounted the cylinder B, in which operates the piston 0, provided with two piston-rods,D and D, extending from the sides of the saidpist0n and connected at their outer ends with a chain or rope, E or E, respectively, each passing over the periphery of a segmental arm, F or F, and fastened to the same by adjustable bolts, so as to permit of taking up all theslack in the chain. The segmental arm F is secured on the transverse shaft G, mounted in suitable bearings on the frame A, and carrying on the outside of the said frame A a disk, H, connected by a link, I, with the crank-disk J, secured to the main shaft K, mounted in suitable bearings in the middle of the frame below the cylinder B.

The main shaft K carries a fly-wheel, L, and an eccentric, N, provided with the eccentricrod 0, slotted at its upper ,end, in which slot is placed, between two springs, P and P, a sliding box, Q, connected with the arm R, secured on the valve-shaft S, carrying the oscillating valve T, placed in the valvechamber U, and operating over the inlet-ports a and I) and the exhaustport c, of the usual construction and arrangement.

The steam supply pipe V connects with the valvechamber U, and the pipe W connects in the usual manner with the exhaust-port c.

The segmental arm F is fastened on the transverseshaft G, mounted in suitable bearings on the frame A, and provided on the outside of the said frame with a disk or crankarm, H, connected by the link H with the disk H.

The operation is as follows: The piston Gin the cylinder B operates in the usual manner by the pressure of the steam being admitted to the cylinder by the oscillating valve T, operated from the main shaft K by the eccentric N. The forward and backward motion of the piston B imparts an oscillating motion to the shafts G and G by means of the piston-rodsD and D, the chains E and E, and the segmental disks F and F. The oscillating motion of the shaft G is converted into a rotary motion imparted to the main shaft K by means of the disk H, the link I, and the crank-disk J.

It will be seen that when the piston B travels to the right the shaft G is oscillated in the direction of the arrow a, as the chain E, connected with the piston-rod D, pulls on the segmental arm F, and when the piston B travels to the left the shaft G is oscillated by the pulling of the chain E connected with. the pistonrod D, on the segmental arm F.

The oscillation of the shaft G is transmitted to the shaft G by means of the disks H and H and the connecting-link H so that the shaft G receives a continuous oscillating motion by the forward and backward stroke of the pisdisk on the said shaft, and a link connecting the said crank-disk with one of the said disks on one of the shafts, so that the oscillating motion of the latter is converted into rotary motion which is imparted to the main shaft, substantially as shown and described.

2. In a steam-engine, a cylinder, a piston traveling in the same, and piston-rods extending at each side of the said piston, in combination with segmental arms connected by chains to the said piston-rods, shafts carrying the said segmental arms, disks attached to the said shafts, and a link connecting the said disks with each other, substantially as shown and described.

adjustable chain E, connected with the said segmental arm F, the piston-rod D, connected with the said chain E, and the piston O, travcling in the steam-cylinder A, in combination with the piston-rod D, attached to the said piston G on the opposite side to that on which the rod D is attached,the adjustable chain E, connected by one end to the said piston-rod D, the segmental arm F, carrying the other end of the said chain E, and the shaft G,on which the said segmental arm is fastened, substantially as shown and described.
